The document discusses parallel processing and pipelining. It describes four types of parallel processing: single instruction stream single data stream (SISD), single instruction stream multiple data stream (SIMD), multiple instruction stream single data stream (MISD), and multiple instruction stream multiple data stream (MIMD). It then uses an example of a laundry process to illustrate how pipelining can be used to increase throughput. Pipelining involves dividing a process into sequential stages that can operate concurrently on different tasks to improve efficiency.
This document discusses pipelining in microprocessors. It describes how pipelining works by dividing instruction processing into stages - fetch, decode, execute, memory, and write back. This allows subsequent instructions to begin processing before previous instructions have finished, improving processor efficiency. The document provides estimated timing for each stage and notes advantages like quicker execution for large programs, while disadvantages include added hardware and potential pipeline hazards disrupting smooth execution. It then gives examples of how four instructions would progress through each stage in a pipelined versus linear fashion.
There are two types of data transfer schemes: synchronous and asynchronous. Synchronous uses a common clock signal where the processor addresses a device at t0, the device places data on the bus at t1, and the processor reads the data at t2. Asynchronous replaces the clock with ready and accept control signals, where the ready signal indicates the device is ready to accept data and the accept signal confirms the data was received.
This document discusses different techniques for transferring data between input/output (I/O) devices and the central processing unit (CPU). It describes programmed I/O, interrupt-driven I/O, and direct memory access (DMA). Programmed I/O involves the CPU continuously checking I/O device status, wasting CPU time. Interrupt-driven I/O improves efficiency by allowing devices to interrupt the CPU when ready. DMA is most efficient as it transfers data directly between memory and I/O devices without using the CPU, which then regains control after the transfer.
This slide contain the description about the various technique related to parallel Processing(vector Processing and array processor), Arithmetic pipeline, Instruction Pipeline, SIMD processor, Attached array processor
This document discusses asynchronous and synchronous communication. Asynchronous communication transmits data intermittently without an external clock, with timing encoded in the symbols. It is used for variable bit rate applications like file transfers and email. Synchronous communication transmits data in a steady stream at a constant rate, requiring synchronized clocks, but allows more data transfer. It is used for real-time applications like telephone calls. Both methods have advantages and disadvantages related to overhead, speed and clock synchronization.
The document discusses various aspects of I/O organization in a computer system. It describes the input-output interface that provides a method for transferring information between internal storage and external I/O devices. It discusses asynchronous data transfer techniques like strobe control and handshaking. It also covers asynchronous serial transmission, different modes of data transfer like programmed I/O, interrupt-initiated I/O, and direct memory access (DMA).
Synchronous data transfer involves sharing a common clock between a CPU and I/O interface so that data transfer is coordinated. Asynchronous transfer has independent clocks, so handshaking methods like strobe control and handshaking are used. Strobe control uses a single strobe pulse to indicate valid data. Handshaking adds a second control signal for acknowledgment between units. This ensures the source knows data was received and the destination knows data is available.
pipelining is the concept of decomposing the sequential process into number of small stages in which each stage execute individual parts of instruction life cycle inside the processor.
The document provides an overview of the basic components of a computer system, including hardware, software, and peopleware. It describes the major internal hardware components such as the system unit, motherboard, CPU, memory, power supply, storage devices, and ports. It also discusses input devices like keyboards, mice, and scanners, as well as output devices including monitors, printers, and speakers. The document defines system software and application software. It concludes by stating that peopleware refers to the people involved in operating computer systems.

The document discusses a colloquium presentation on diamond chips. Diamond chips are manufactured from diamond structured carbon wafers and use carbon nanotubes as their major component. To make diamond conductive for electronics applications, it must be doped with elements like boron or nitrogen. Carbon nanotubes have excellent electrical and thermal properties and high strength. They allow for smaller, faster components that can operate at high temperatures. While diamond chips provide advantages over silicon, their production is more expensive and doping is more difficult due to diamond's structure. Overall, the presentation suggests that carbon chips may replace silicon in electronics in the future.
